Heatwaves pose severe risks to human health, particularly for vulnerable groups such as the elderly, individuals with chronic illnesses, and outdoor workers. Prolonged exposure to high temperatures can lead to heat exhaustion, heatstroke, and acute kidney injury. Additionally, heatwaves can exacerbate existing health conditions, including cardiovascular and respiratory diseases. Socioeconomic impacts include reduced labor productivity and disruptions to essential services like healthcare and transportation. Urban areas are particularly affected due to poor housing designs and loss of greenspace, which amplify heat exposure. The WHO highlights the urgent need for climate action and preparedness to mitigate these risks.
